RICANA (Radar Imaging, Challenges And New Approaches)

RICANA ("Radar Imaging: Challenges And New Approaches”) is a recently launched European Project funded through the FP7-PEOPLE_IOF Programme. The RICANA project is concerned with the improvement of Radar Imaging technology and its application to Ground Penetrating Radar (GPR), or Through Wall Radar (TWR) systems. The general milestone of the RICANA project is to achieve novel advances in the Radar Imaging field so that a disruptive technology can emerge.

 

Objectives

 

The desired progress cannot be undertaken without solving previously known technological challenges. It becomes essential, in the first place, to determine the electromagnetic behaviour for the usual materials disposed between the sounder and the objectives targets, based on its spectral signature, in order to correctly design a reliable detection system. Once determined this behaviour, a research field is opened for the optimization of these systems and their different components and subsystems. The further step is the design of transmitting and receiving antennas adapted to the characteristics of the elements to detect. Also there is place for the research of other aspects of the sounding, like the optimization of the transmitted signal, alternative receiver schemes, and the processing algorithm of the received signal.

This project is funded by the 2008 IOF Marie Curie Actions (EU FP7 People Program) and this grant extends from June 2009 to December 2011. The participants are the Radio Systems Research Group of the University of Vigo (Vigo, SPAIN) (UVIGO) and the EMAG Research Group of the New Mexico State University (Las Cruces, NM, USA) (NMSU). The scientist in charge is Prof. Manuel Garcia Sanchez in UVIGO and Dr Muhammad Dawood in NMSU. The fellow researcher is Dr Ana Alejos.

Outcomes

Up to present, the outcomes surpassed the initial objectives and the more noticeable result has been the achievement of the experimental demonstration of an electromagnetic phenomenon related to the dispersive nature of media such as soil, water, vegetation, tissues, metal and so on.

The dispersive propagation occurring in these media produces the arise out of a waveform known as Brillouin precursor which has slept down on scientific textbooks since its theoretical prediction in 1914 due to the mathematical and computational difficulties to board the study as well as the technical challenge to demonstrate their practical existence.

Theoretically, the Brillouin precursor can provide larger penetration depths into a dispersive medium compared to that achieved by the conventional single frequency or narrow-band signals, thereby providing: (i) enhanced signal-to-noise ratio (SNR) and thus better imaging through hard-to-image dispersive media; and/or (ii) larger propagation distance for the same transmitted power, or conversely less transmitted power to achieve the same distance for a given receiver sensitivity, hence contributing to “green technologies.

Brillouin precursors carry a significant portion of the energy of the propagating ultrawideband pulse in any dispersive attenuative media, thereby delivering either more power at the same distance, or larger distance, and/or both.

 

 

Neglecting these field means to eliminate an important and significant part of the received signal energy. It is therefore reasonable to conclude that Brillouin precursors have a large potential to impact positively the ground penetrating radar, through-the-wall imaging, imaging through seawater and leafy foliage, communication through foliage and seawater, non-destructive testing, material characterization, etc. So, alongside the remaining WPs of the RICANA project we have considered the dispersive propagation phenomenon in order to achieve an optimal system design and signal data processing.

The correct design of the radiating elements and also the suitable transmitted signal become key elements which must be analyzed under the light of the Brillouin precursor formation. These outcomes have reached a large impact on the international scientific community and it has been rewarded through the rapid publication of journal papers. Different conference papers have been also accepted and presented, and many other publications are under review process and elaboration. We can mention among other outcomes, a pending patent presented to protect the intellectual property on the measurement technique developed to detect and characterize the dispersive phenomenon of the Brillouin precursor waveforms.

The research team considers that with the work performed around the Brillouin precursor phenomenon, this break-up technology is stated to be practically possible and especially, the analysis performed can help to introduce important improvements in the imaging techniques under use at present.
